29-Inch Plus Wheel

Surly's Krampus rolls fast, holds speed, and devours corners. It's designed for 29 x 3-inch tires, offering increased traction, incredible float, huge rollover, and low-fi suspension to take your trail ride to new heights of fun. Surly built this frame and fork out of tapered and butted chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. Boost front spacing keeps you current with the latest MTB tech, and, "Gnot Boost," rear spacing means you can run any the rear hub you want: 135 x 10 QR, 142 x 12mm, or 148 x 12mm thru axles. This frameset also offers internal dropper post routing so you're granted a license to get rowdy, which you really can't help but do on a Krampus.

The ECR is Surly's answer to those times when you just need to escape to the woods for a while to get away from the humdrum of life. Those familiar with this steel mule know it’s designed around plus tires, previously of the 29” variety. A fully loaded 29+ bike is an excellent way to explore and get away for a while… if you’re of a certain stature that is. For smaller riders, it poses several challenges though. And no one wants new problems when they’re in the woods trying to escape old ones. To solve this, Surly redesigned the smaller sizes of the ECR to work with 27.5+ while the larger sizes are still equipped with 29+. All you medium specimens out there get your pick of the litter as they're offering that size in both options.
Other updates to the ECR include and are limited to: Gnot-Boost rear spacing and a killer new beige paint job. It retains the abundant accessory mounts that we all know and love like Surly Trip Guide for brakes and derailleurs, fender, rack, and Bill/Ted eyelets, and a Rohloff torque arm slot. The 29+ sizes have two water bottle mounts and one set of Three-Pack bosses. You’ve got lots of options to bring all your “necessities” with you and still have room for excess baggage if you’ve got it.

The 29 x 3-inch Dirt Wizard tires on 40mm Alex rims take your trail ride to new heights of fun. These big tires offer increased traction, incredible float, and reduce the need for suspension because the large volume is plenty to smooth the trail. You'll also get a SRAM NX 1x drivetrain, Answer Pro Taper bars, and SRAM Level hydraulic brakes to make you the new master of terrain that used to be out of bounds.
